             Summary: JettyWebSocketServer uses original requested port, instead of the forwarded port
                 Key: NIFI-3561
                 URL: https://issues.apache.org/jira/browse/NIFI-3561
             Project: Apache NiFi
          Issue Type: Bug
          Components: Extensions
    Affects Versions: 1.1.0
            Reporter: Edgar Orendain


Situation:
We have port forwarding set up in such a way where port 25000 is forwarded to port 15000.  ListenWebSocket processor listens on this 15000 port.

Requests that hit the JettyWebSocketServer are considered as attempting to connect to the original port (25000) rather than the forwarded port of 15000.  The same was reproduced with different ports and on different forwarding layers (i.e. NAT and iptables).  I've included a stack trace below.

From Koji:
I think it's more of a Jetty side issue, after it upgrade HTTP connection to TCP, it still uses the original requested port (which is a port forwarding request to the real port) to find a request handler assigned to that port.
